Erigeron is a genus of around 200 annuals, biennials or perennials with simple or lobed leaves, and daisy-like flowers with many slender rays, appearing over a long period in summer.
They grow in dry grassland and mountainous areas, with a wide distribution that is concentrated around North America. They range from small alpine species to tall, bushy plants.
Fleabanes make a good plant for a mixed border, thrive in coastal conditions, and make good cut flowers.
E. karvinskianus is a perennial forming wide mats to 15cm in height, with narrow, hairy leaves and daisy-type flower-heads 15mm in width, opening white but soon turning pinkish-purple.
